Medium-sized brownish bird of the lower subtropical zone in the western Andes of Colombia and Ecuador. Plain dark brown with much less streaking than other treehunters; only shows a slightly paler eyebrow and some streaking on the throat. Typically found at lower elevations than other treehunters in range, but some overlap. Western Woodhaunter is found at similar elevations but has a longer, narrower bill and a paler buffy throat. Singles or pairs follow mixed-species flocks through the understory, where they can be skulky and difficult to see. Listen for the song: a slow series of 5-10 squeaky notes.
